Y STONE andHnNRY THOMAS JoHNsoN, subside plating of the vessel though attached/i jects of the King of Great Britain and 1re-i land, residing at Sunderland, inthe county Y of Durham, England, `have n invented new and useful Improvements in CargoVessela of which the following is a specification.

carrying oil and other liquidsin bulk. yTank vessels have been proposed having a number of vertical cylindricaltanks formed fbya' series of semi-circular bulkheads extending between and directly connected to-thesides of the vessel so that said tanks `form partof the structure of the vessel, such construction being primarily designed to4 attainl unit l spaces so large as to be suitable for stowin@ general cargo when not used orliqui cargo."` Such vessels have been' provided with side `tanks formed between the convex sides of A `he bulkheads and separated by central longitudinal partitions.

The present invention provides ,a *cargo vessel having an improved yconstruction vof tanks solely intended for carrying oil andV other liquid in bulk, such construction resulting in increased ',strength, safetyM and stability.

According to kour invention `we providel aj cargo vessel with a number of cylindrical tanks, said tanks being independent .of the thereto, each main tank being provided with a smaller cylindrical tank or tanks. f Seg-l whereinf Figurel is an outline plan of a cargo ves-` sel iny accordance with our invention; andv l Fig. 2f isa central longitudinal sectionl of Fig. l.

almost equal to Ythe distance between the u sides el, el, of the ship at they point where the tank is situated, and "theaXes Yof the tanks lying in the plane of the `fore-and-a'ft center line of the vessel. rlhe main'tanks c-c are suitably constructed of curvedV plating strengthened where requiredby brackets ory stiteners.
